This prospective observational cohort study is an extension of a previous study reporting effects of cytomegalovirus ( CMV ) on graft and patient survival in 471 patients who underwent kidney transplantation between 1994 and 1997. CMV pp65 antigen was measured every 7–14 d during the first three months after transplantation, given as number of CMV pp65‐positive cells per 10 5 leukocytes. A positive test was defined as CMV infection. None of the patients received CMV prophylaxis or preemptive treatment. During a median of 13.7 (7.1–14.9) yr, the number of death‐censored graft losses was 118 (25%) and of patient deaths 224 (48%). CMV infection was an independent significant risk factor for mortality in multivariate analysis ( HR  = 1.453, 95% CI 1.033–2.045, p = 0.032), adjusting for patient and donor age, preemptive transplantation, HLA ‐ DR and ‐ AB mismatches, living donor, acute rejection during the first three months, donor–recipient CMV IgG antibody status and diabetic nephropathy. In univariate analysis, CMV infection was significantly associated with death‐censored graft loss but the association was not significant in multivariate model. CMV infection early after kidney transplantation is a predictor of overall mortality but not of death‐censored graft loss after a median observation period of 13.7 yr.
